STOP-MOTION MECHANISM FOR SPOOLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 375,598, dated December 27, 1887.

Application filed July 14, 1887. Serial No. 244,252.

To aZZ whom it may concern: 1

Be it known that we,LOUIs G. BILLINGs and- ARTHUR W. PARKHURST, both residents of Milford, in the county of Hillsboroughand State of New Hampshire, have invented certain new and useful Improvements in Stop- Motion Mechanism for Spooling- Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of so much ofaspooling-machine as is necessary to illustrate our invention, some of the parts thereof being shown in section for the better illustration of the several operative parts of the device thus shown. Fig. 2 is a top view of the revolving drum and a spool and the adjacent parts of the frames. Fig. 3 is a perspective detail view of the drum and spool and the adjacent parts of anism for immediately stopping the machine if the yarn or thread should break, as will be hereinafter fully described and claimed.

Referring to the several parts by letter, A indicates the outer frame-work of the machine, in one end of which is mounted the vertical spindle B, which rotates the drum which revolves the spool. This spindle is mounted in bearings at its upper and lower ends, so as to turn freely, and on its lower end portion is loosely mounted a pinion, O, which meshes with the gear-wheel D, which drives the pinion, and through it drives the spindle B. This pinion (J turns loosely on the lower end of the spindle when the clutch E is thrown out of engagement with it, and has formed inits up per side or top a recess, F, and a series of recesses, F, in the bottom of the said recess, for the purpose hereinafter described.

(No model.)

On the lower end portion of the spindle B, just above the pinion O, is mounted the double clutch E, which consists of a sleeve, G, on the lower end of which is mounted a clutch-disk, H, which is formed with the series of down wardly-projecting lugs I on its lower face, which are adapted to enter the recesses F in the top of the pinion 0 when the clutch-sleeve is moved down on the spindle, the lower part of the lower disk, H, fitting down into the large recess F in the top of the pinion O, and thus guiding the projections I on the lower face of the disk H down into the recesses F, in which they fit, as will be readily understood. On the upper end of the sleeve G is secured another clutch-disk, J, the upper face of which is formed with a series of radial corrugations or grooves, J, running from the center thereof toward the outer circular edge of the disk,and 0 adapted to engage with the grooves or corrugations K, which are formed on the lower side of the free end of a projecting arm, K, when the sleeve G is moved up by the breaking of the thread or yarn, the said grooves K diverging from the outer end of the said arm K,

so as to conform with and register with the radial corrugations J ofthe upper clutch-disk,

J. The sleeve G is formed in one side with a longitudinal slot, G, through which extends a lug or finger, B projecting from that part of the spindle B, so thatthe spindle must revolve or stop with the said clutch-sleeve.

In Fig. l of the drawings we have, for convenience in illustrating the device, indicated the position of this lug or finger B although in reality it would be concealed from View b the fork of the lever L.

L indicates a centrally-pivoted lever, the bifurcated inner end, L, of which fits around that 0 side of the clutch-collar between the upper and lower disks of the same, while to the outer end,

L of this lever, near the extremity of the same,

is pivoted the lower end of a rod, M, the upper portion of which passes up through a ver tical slot, N,in a rearwardly-projectingstationary arm, 0, and is formed with a shoulder, M,which is adapted to engage with the upper side of the slotted arm when the upper end of the rod M is drawn out by taking hold of the 10: upper ringed end or handle, M. Upon the upper side of the arm 0, to the outer side of the slot N, is pivoted between the two lips P P the inner lower end of a lever, Q, the outer end of which is preferably formed of a wire having its outer upper end bent to form an eye, B, through which the yarn or thread passes.

The yarn or thread passes from the cop or reel S over the guide wires or rods (4 wand through the eye R, this eye It at the outer end of the lever Q being thus drawn up and held in an elevated position about between the said guide-wires as the thread or yarn passes through the eye R over the said guide-wires and then around the spool on which it is being wound; but if the yarn or thread should break on its passage from'the cop to the spool the outer end of the finger or lever Q will fall, and the inner lower part of its pivoted end, which is eccentrically pivoted and formed with a point, Q, on its lower inner side, will come in contact with the outer side of the upper part of the rod M, and thus force the shoulder M back clear of the outer end of the slot N, when the outer end of the centrally-pivoted lever L is drawn down by a spring, T, arranged as shown, and as the outer end of the said centrally-pivoted lever is drawn down its inner bifurcated end is swung up, and thus slides the collar G up on the spindle B, so as to free its lower clutch-disk, H, from the pinion O,when the said pinion G continues to revolve on the lower part of the spindle without affecting the spindle, and as the double clutch is thus raised the upper clutch-disk, J, engages with its upper corrugated face with the series of grooves K in the lower face of the stationary short arm K, and as the sleeve G is formed with a longitudinal slot, G, through which passes and slides a stop or pin, 13, on the spindle B, it will be seen that as the lower end of the double clutch is freed from the pinion which drives the spindle the upper end of the said double clutch will engage with the grooved stationary arm K, and that the revolution of the spindle will thus be stopped with a positive action.

It will thus be seen that as soon as the thread or yarn breaks the before-described mechanism operates automatically with apositive stop motion to stop the revolution of the spindle,

and consequently of the spool itself. It will be seen that this mechanism is very simple in construction and exceedingly effective in its operation.

The spool is revolved in the following manner: Upon the upper end portion of the spindle B is firmly mounted a drum, A, which is formed of wood or other suitable material, and which may be covered or not, as preferred. This drum is of such length as to fit against the body or barrel of the spool on which the thread is being wound between the ends or heads of the same, as shown in the drawings. To one side of the drum A is pivoted the upper end of a bracket, B, which is formed with the lower and upper projecting arms, B and 13*, respectively, the lower arm being formed with an upwardly-projecting pointed conical bearing, B, while the upper arm is formed with a transverse slot, B extending in from one side thereof. The outer end of the bracket in which the spool is mounted is drawn in toward the drum A by the tension of a spring, 0, so as to always hold the spool in contact with the said drum, and to permit of the bracket gradually swinging outward as the thread is wound upon the spool.

In operation the spool is placed in position in the bracket, as shown, the slot 13" being on that side of the upper arm of the bracket toward or next to the drum, and the tension of the spring 0 then draws the spool in to the drum until the drum is in contact with its barrel. The spindle is then started by sliding down the double clutch E, as before described, and as the spindle rapidly revolves the drum A will rapidly revolve the spool around which the thread or yarn is being wound; and it will be seen that when the winding begins the large drum is bearing against the almost empty spool, against the body or barrel thereof, which at the start,before any thread has been wound upon it, is only about one-third the diameter of the drum with which it is in contact, and it will thus be seen that at first the spool will be revolved three times for one revolution of the drum, while when the thread is wound upon the spool the speed of the spool will gradually decrease as the diameter of the spool gradually increases and approaches that of the drum, as will be readily understood. It will thus be seen that by employing this drum the device operates automatically to regulate the speed of the spool, and that thus a gain of about twenty-five per cent. in the amount of work performed is attained by gaining the great rate of speed when the spool begins to fill. An even pressure of the drum against the spool is secured by the spring 0, the spring thus not only operating to hold the drum always in operative contact with the spool, but also assisting in causing the thread to be evenly and smoothly wound upon the spool, an even tension being thus obtained.

E indicates a transverse guide-rod, over which the thread is passed. before winding.

around the spool.

Instead of the two parallel guide-rods a a, these rods may be dispensed with and a bar, a, having the curved or rounded outer side, employed instead, in which case the thread before passing through the eye R passes up and over the curved side of the bar a, and then through the eye, by which arrangement the eyed end of the lever Qwill be held up in its elevated position, as shown in the said view.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of our invention will be readily seen and understood. It will be seen that the construction of the several parts is very simple and strong, and that they are exceedingly efficient in their operation. The automatically-operating positive stop-motion mechanism will stop the revolution of the spindle as soon as the thread or yarn breaks.

Having thus described our invention, what we olaim,and desire to secure by Letters Patent of the United States, is

In a machine for spooling yarn, thread, or silk, the automatic stop mechanism consisting of the combination, with the spindle having the projecting pin or stop near its lower end, of the revolving pinion loosely mounted on the lower end of the spindle and formed with the recesses in its upper side, the double clutch consisting of the sleeve formed with the longitudinal slot, having secured on its lower end the clutch-disk formed with the lower projections and having on its upper end the disk formed with the radial corrugations in its upper face, the stationary arm having the grooved lower end, the centrally-pivoted spring-actuated lever having the bifurcated inner end, the stationary outwardly-projecting arm formed with the vertical slot, the rod pivoted at its lower end to the outer end of the centrallypivoted lever, formed with the shoulder on its outer side and having the ringed upper end, and the eccentrically-pivoted lever formed with the eye at its outer upper end, substantially as set forth.

In testimony that we claim the foregoing as our own we have hereunto aflixed our signatures in presence of two witnesses.
